What certificates need to be specified for ssl on websocket?

Question

go

ssl_certificate /etc/nginx/ssl/private.crt;
ssl_certificate_key /etc/nginx/ssl/private.key;
There are some that give error 1015.

err := http.ListenAndServeTLS(":8081",
    "/etc/nginx/ssl/private.crt",
    "/etc/nginx/ssl/private.key", nil)
if err != nil {
    fmt.Println(err.Error())
}

Answer 1

Exactly the same as not on websocket.
If you still have nginx in the chain, then it's easier to entrust https to it, and forward it to the backend via

client_max_body_size 0;
proxy_http_version 1.1;
proxy_pass http://your.websocket.backend/;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
